Wife traded her Whites XLT for a Garrett GTI 1500 (used) she is real happy with it, in the house, the only thing she didn't like was there was a little play where the stems connect. I told her I thought someone on the forum had the same problem and came up with a way of tightening them Was I right? If so please let me hear. If not can any one help, also would that little play effect the imaging?
